Anyone who has seen the classic rabbit-duck optical illusion knows the magic and confusion of duality. One might see a duck facing to the left with its bill hanging slightly open or a rabbit with its nose pointing to the right and its ears extending behind it. Both perspectives are valid. In physics, duality is when a single physical system can be described with two completely different sets of equations.

It was already a mind-bending shift, last century, to go from Isaac Newton’s absolute space and universal time to Albert Einstein’s four-dimensional space-time, which is dynamic, flexible, sensitive to the touch. Einstein’s general theory of relativity showed that mass and energy warp the geometry of space-time, carving out strange contours of the universe, which suddenly became a place that could begin or end.

A metafísica é o ramo da filosofia que lida com a estrutura profunda do mundo: a natureza do espaço, do tempo, da causalidade e da existência, os fundamentos da realidade em si. Em geral, é considerada não testável, uma vez que as suposições metafísicas são a base de todos os nossos esforços para fazer testes e interpretar resultados. Essas suposições geralmente passam despercebidas. Na maioria das vezes, isso não chega a ser um problema.

IntroductionMetaphysics is the branch of philosophy that deals in the deep scaffolding of the world: the nature of space, time, causation and existence, the foundations of reality itself. It’s generally considered untestable, since metaphysical assumptions underlie all our efforts to conduct tests and interpret results. Those assumptions usually go unspoken. Most of the time, that’s fine. Intuitions we have about the way the world works rarely conflict with our everyday experience.

Science has been missing something. Something central to its very existence, and yet somehow just out of view. It is written out of papers, shooed away, shoved into laboratory closets. And yet, it’s always there, behind the scenes, making science possible.

On a February morning in 1935, a disoriented homing pigeon flew into the open window of an unoccupied room at the Hotel New Yorker. It had a band around its leg, but where it came from, or was meant to be headed, no one could say. While management debated what to do, a maid rushed to the 33rd floor and knocked at the door of the hotel’s most infamous denizen: Nikola Tesla. The 78-year-old inventor quickly volunteered to take in the homeless pigeon.
